19. 4x-y+2z = 8x+y-4 Find x

Mathematics
1 answer:
Varvara68 [4.7K]3 years ago
4 0

Answer:

x = \frac{4-2y+2z}{4}

Step-by-step explanation:

4x-y+2z = 8x+y-4

4x-8x-y+2z = 8x - 8x +y-4

-4x -y +2z= y-4

-4x -y+y +2z = y+y-4

-4x +2z = 2y-4

-4x+2z-2z = 2y-2z-4

-4x = 2y-2z-4

x= \frac{2y-2z-4}{-4} = \frac{4-2y+2z}{4}

Tyler has a baseball bat that weighs 28 ounces. Find this weight in kilograms and in grams.
brilliants [131]

Answer

28 ounces = 793.79 grams

28 ounces = 0.79 kilograms.

Step by step explanation

1 ounce = 28.3495 grams

Now let's convert 28 into grams.

Here we have to multiply 28 by 28.3495

28 x 28.3495 = 793.787 grams

Now let's convert 793.787 into kilograms

1 kilograms = 1000 grams

793.787 grams = 0.79 kilograms

Figure TUVS is a parallelogram.
poizon [28]

Angles T and V of the parallelogram are equal to 91°.

Calculating the Value of x

In the parallelogram TUVS, adjacent angles U and V are given as,

U = 4x+9

V = 6x-29

Since U and V are adjacent angles, and as per the properties of a parallelogram, sum of adjacent angles is equal to 180°.

4x+9 + 6x-29 = 180

10x - 20 =180

10x = 200

x = 20

Calculating the Angles of the Parallelogram

∠U = 4x + 9

∠U = 4(20) + 9

∠U = 80 + 9

∠U = 89°

∠V = 6x - 29

∠V = 6(20) - 29

∠V = 120 - 29

∠V = 91°

According to the properties of a parallelogram, opposite angles are of equal measure.

∴ ∠T = ∠V and ∠S = ∠U

⇒ ∠T = 91° and ∠S = 89°
